Can't connect to any channels on Acestream anymore

Good morning all,

This weekend I have been unable to connect to any sports streams or Acestream.

I have reinstalled Aceplayer and updated to the latest version of Flashplayer.

I can see video & audio from utube and other sites.

My UK ISP is Virgin Media. Is there a possibility that they are blocking all sports streams?? as my father had no problems accessing using his ISP Sky UK. or is it more likely that I have deleted something by mistake.

Was going to try a Proxy Server to see if that resolves, not sure how I cab check they are blocking?

Any assistance would be invaluable.
